Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "In the alpha-mgmt network, open the SSH port 22 to all servers with the network tag alpha-server."

A block of code is set as follows:

#! /bin/bash
apt-get update
apt-get install -y apache2
cat <<EOF > /var/www/html/index.html
<html><body><h1>Hello World</h1>
<p>Web server on the alpha and beta networks</p>
</body></html>
EOF

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

### Hardcoding tokens in a program is never a good idea. This can be used only for learning ###
access_token = ""
access_token_secret = ""
consumer_key = ""
consumer_secret = ""

Any command-line input or output is written as follows:

$ sudo echo "1 rt1" >> /etc/iproute2/rt_tables

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Choose the Automatic option under Subnet creation mode."

Warnings or important notes appear like this.
Tips and tricks appear like this.
